Due to the increase in the number of users and new applications with higher data requirements, the use of data in wireless communication networks is growing. However, for each user-f', a given network typically has a certain maximum supported data transmission rate, which is determined by the network design. The substantial increase in the maximum supported data transfer rate is often achieved by deploying new or new network designs. For example, the cellular network has provided a substantial improvement in data transmission rates and characteristics from the second generation (2G) to the third generation (four). However, the new network deployment is expensive and often complicated. Therefore, several techniques are needed in the art to improve the throughput of users in wireless communication networks in an efficient and cost effective manner.

The transmission techniques described herein can be used in a variety of wireless communication networks, such as CDMA, TDMA, FDMA, and OFDMA networks. The terms "network" and "system" are often used interchangeably. A CDMA network may implement one or more radio technologies, such as cdma2000, wide time slot CDMA (W-CDMA), and the like. Cdma2000 covers IS-2000, IS-856, IS-95 and other standards. The TDMA network may implement one or more radio technologies, such as GSM, Global Evolution Enhanced Data Rate Technology (EDGE), and the like. These various radio technologies and standards are well known in the art. W-CDMA and GSM are described in the literature entitled "3rd Generation Partnership Project" (3GPP) Association. In the literature named "3rd Generation Partnership Project 2" (3GPP2) Association Cdma2000 is described. The 3GPP and 3GPP2 documents are publicly available. For the sake of clarity, the transmission techniques are specifically described below for the GSM network, and the GSM terminology is used in the following extensive description. The GSM network can be a GSM EDGE Radio Access Network (GERAN) or some other GSM network. Figure 1 shows a GSM network 100 having a base station and a mobile station 120. A base station is typically a fixed station that communicates with a mobile station and may also be referred to as a Node B, a Base Transceiver Subsystem (BTS), an access point, and/or some other terminology. Each base station 110 provides communication coverage for a particular geographic area 102. The term "honeycomb unit" may refer to a base station and/or its coverage area, depending on the context in which the term is used. The network controller 130 is coupled to the base station 110 and provides coordination and control of such base stations. The network controller 13〇 111368.doc 1375476 can be a collection of a single network entity or a network entity. For example, network controller 130 can include a base station controller (BSC), a mobile switching center (MSC), and the like. The mobile stations 120 are typically dispersed throughout the network, and each mobile station can be fixed or mobile. A mobile station may also be referred to as a user equipment, terminal, subscriber station' or some other terminology. The mobile station can be a cellular phone, a personal digital assistant (PDA), a wireless communication device, a palm-sized device, a wireless data device, and the like. The mobile station can communicate with the base station on the downlink and/or uplink. The downlink (or forward link) represents the communication link from the base station to the mobile station' and the uplink (or reverse link) represents the communication link from the mobile station to the base station. The GSM network can operate on one or more frequency bands, such as the GSM 900, GSM 1800, and GSM 1900 bands. Each frequency band covers a specific frequency range and is divided into a number of 200 kHz RF channels. Each RF channel is identified by a specific ARFCN (absolute RF channel number). Table I lists the frequency ranges for the downlink and uplink and the ARFCN for the GSM 900, GSM 1800 and GSM 1900 bands.

In order to reduce the cellular unit I11368.doc 1375476 Interference 'The base stations set up close to each other are assigned different sets of RF channels so that the transmissions of these base stations do not interfere with each other. Figure 2 shows the frame structure in GSM. Divide the transmission schedule into several hyperframes. Each hyperframe has a duration of 6 · 12 seconds and includes 1 326 TDMA frames. The super frame can be divided into 5 1 26-frame multi-frame or 26 51-frame multi-frame β 26 frame multi-frame is usually used for the traffic channel, and the 51 frame multi-frame is usually Used to control the channel. Each % framed multiframe lasts 120 milliseconds (ms) and includes 26 TDMA frames identified as TDMA frames 0 through 25. The traffic data can be sent in TDMA frames 0 to 11 and TDMA frames 13 to 24 of each of the 26 frame type multiframes. Each of the 51 framed multiframes lasts for 235.365 ms and includes 51 TDMA frames, which are identified as TDMA frames up to 50. The parent-TDMA frame lasts 4.615 ms and is divided into 8 time slots, identified as time slots 0 through 7. The transmission in each time slot is called "• 丛 ” in GSM. The publicly available title is "Technical Specificati〇n Group GERAN, Digital cellular telecommunications system (Phase 2 + ); Physical layer on the radio path The frame structure for GSM is described in 3Gpp TS 05.01 of "General description" (version 1999 '2001 ^ month). In an exemplary embodiment, the GSM network supports multiple bearer operations for the downlink (DL) and/or uplink (UL). The mobile station can receive data on multiple RF channels while performing multiple bearer operations on the downlink. The mobile station can transmit greed on multiple RF channels while performing multi-carrier operation on the uplink. Depending on various factors, such as the availability of radio resources, U\36S.doc 1375476

Material requirements and line-of-service capabilities, towering, can be assigned to one or more of the downlinks or multiple RF channels for the uplink. The terms "RF channel" and 载体 are used, and the carriers are used interchangeably herein. For the sake of clarity, the following description of the large number of 0# linings is a multi-carrier operation of a mobile station. The station may assign any number of time slots for each of the carriers of the downlink and uplink for each of the time slots, or the number of time slots may be

Assigned to different carriers. The A-slot can be assigned the same number of time slots on all DL carriers, and can be 蛀芏-β丄 and the receivers have equal transmission capabilities on all DL carriers. For example, action can be pulled, >, ^ 仃. It can receive the assignment of (4 + 4) + 2 time slots, which means that four time slots are used for the two DL carriers in the Helmet. R ^ y is the mother of 1P and two time slots are used for one UL. Carrier. The mobile station also has a different number of time slots for the DIj carrier. For example, the mobile station can dd / /a, . Receive (4 + 2) + 2 time slot assignment, which means that four time slots are used for one DL carrier and two time slots are used for the other -DL carrier. Two time slots are used for one UL carrier. The number of time slots assigned for each link may be ambiguous depending on various factors, such as the factors noted above for carrier assignment. The assignment of time slots and carriers is typically semi-static and is controlled by the GSM network via the upper layer signals. On the down link, the assigned time slot can be shared with other mobile stations. If the data is sent to the mobile station in the slot for a given assignment, the mobile station is configured with a time slot. The multi-time slot configuration is configured for more than one time slot to the mobile station in the TDMA frame. The configuration of the time slot is typically dynamic and can be controlled by the Media Access Control (MAC) layer in the GSM network on a per packet basis. The packet data block can also be called message, #包,数据块, wireless H1368.doc •10-1375476 Electrical Link Control (RLC) block, RLC/MAC block, and the appropriate method—Sun Huan stays a different term. Each packet data block includes a header indicating the intended recipient of the packet data block. & The mobile station typically performs call setup with the GSM network to obtain the assignment of bearers for the downlink and uplink carriers. The mobile station performs an initial capture before the call is established. For the initial acquisition, the mobile station adjusts to the DL bearer, and the frequency is obtained by processing the frequency correction channel (FCCH), which is obtained by decoding the synchronization channel (SCH). Timing, and self-broadcast control (BCCH) to obtain system information. For call setup, the mobile station attempts to establish an RR connection by transmitting a radio resource (rr) channel request message on the random access channel (RACH). The base station receives the request, assigns one or more bearers to the mobile station for each of the downlink and uplink routes, assigns one or more time slots for each assigned bearer, and assigns one Or multiple traffic channels (TCH). The base station also determines the timing advance and frequency correction for the mobile station based on the received request. Timing advances the timing error at the mobile station. The frequency correction describes the Doppler shift caused by the movement of the mobile station. The base station then transmits the assigned radio resources (carrier and: slot), timing advance, and frequency correction on the access allowed channel (AGCH) to the mobile station. The mobile station applies the timing advance and frequency correction so that the time and frequency of the uplink transmission from the lamp stage is tuned at the base station. The mobile station then exchanges signals with the GSM network to establish a call (e.g., for use) and/or packet data. Thereafter, the mobile station exchanges data with the GSM network on the assigned carrier and time slot. Initial capture and call setup are described in various documents from 3Gpp. 111368.doc In general, the mobile station can refer to any number of carriers on the subscribed link and any number of B 4 m ^ carriers on the uplink link. The number of DL carriers may be the same as or different from the number of UL· carriers. In the lower right > "4 establishment process, the mobile station can be assigned a downlink link and / or uplink carrier on the uplink" mobile station can also initially assign a Φ ^ , ra carrier for each link 'And then the mobile station can add more 3 signals for each link as needed, and the carrier can be established and split through layer 3, layer 1 signal (eg 'turning the ife neck Similar to packet switched handover) and/or implicit signaling. If the number of DL carrier disks B is 4 in the number of UL carriers, and if there is a fixed mapping between the DL carrier and the UL carrier, then the action The station may send an acknowledgment (ACK) on the UL bearer to θ a — α 〜 polled on the associated DL bearer' and vice versa.

In an exemplary embodiment, 'will per- The bearer on the link is represented as a misdirected bearer for the other hand, and the remaining bearer (if there is a two-two carrier. The subscriber station can perform call setup via the DL and UL staggered bearers. The DL tin fixer can be The assignment of the carrier, time slot and traffic channel of the % downlink and uplink is transmitted to the mobile station. The mobile station can be guided on the anchor carrier and the auxiliary carrier can be established via the anchor carrier. The frequency and timing of a DL bearer assigned to the mobile station. The frequency and timing of the #DL anchor bearer can be obtained based on the FCCH and SCH during the initial acquisition process. Since all dl 12 lU36S transmitted by a given base station .doc 1375476 The time and frequency of the carrier is usually To align, the mobile station can use (10) the timing and frequency of the bearer to obtain the individual sinking carriers more quickly. The mobile station applies the appropriate timing advance and frequency correction to each UL bearer assigned to the mobile station. The exemplary embodiment is assumed to be associated with a sink carrier, and - a common timing advance and a common frequency correction for all UL bearers assigned to the mobile station. In this exemplary implementation, the base station is based on being transmitted by the mobile station (eg, Uplink on the UL staggered carrier;: determinable; t pre-common and common frequency correction. For example, in the packet transfer mode, the mobile station can advance the control channel (PTCCH/U) at the uplink packet timing ( It transmits on the UW fixed carrier) the random access burst. The base station can estimate the timing advance for the mobile station based on the random access burst, and can control the channel ahead of the downlink packet timing (ptcch/d). The heart transmits a timing advance update for the mobile station on the DL anchor carrier. The mobile station can then advance the timing advancement - in the exemplary embodiment, the mobile station transmits on each carrier with the S i takes the burst' and the base station transmits an independent timing advance update for each _UL bearer. The mobile station can transmit signals on the uplink in various ways. In an exemplary embodiment, the mobile station transmits on the UL tin carrier. In another exemplary embodiment, the assigned UL bearer is associated with the assigned 〇 1 carrier. For example, 'depending on the number of bearers assigned for each link, the DL bearer and the UL bearer There is a one-to-one, many-to-one or one-to-many mapping between the mobile stations. The mobile station can transmit signals for each dl bearer III 368.doc 13 1375476 on the associated UL bearer. The mobile station can indicate to the GSM network Synchronization with the auxiliary 1) carrier. In an exemplary embodiment, a synchronization indication of all of the chirp carriers is transmitted on the UL anchor carrier. In another exemplary embodiment, a synchronization indication for each DL bearer is transmitted on the associated ul bearer. In another exemplary embodiment, the synchronization indication is implicit. For example, the GSM network may infer that there is no synchronization since the packet sent to the mobile station on the downlink failed to receive an ACK from the mobile station. This indication can also be delivered in other ways. In an exemplary embodiment, the DL anchor carrier carries the following information: • System Information (BCCH); • Timing Advance for the Mobile Station (PTCCH/D); and • Action Specific Signal (PACCH) for the Mobile Station . The timing advance can be sent on the PTCCH/D and can be used for all UL bearers assigned to the mobile station. In this case, the mobile station does not need to receive the timing advance on the secondary carrier. The action specific signal may be sent on the Packet Associated Control Channel (PACCH) and may include ACK, power control information, resource assignment and reassignment messages of the packet data block transmitted by the mobile station on the uplink, and the like.

Figure 3 illustrates an exemplary embodiment of multi-carrier operation in a GSM network. In this exemplary embodiment, the mobile station is assigned N DL carriers (1 to N) and a plurality of UL carriers (1 to M), wherein in general N21 and M21. A plurality of bearers are assigned for at least one of the multi-carrier operations, thus N > 1 and / or M > The N DL carriers and the UL UL carriers may correspond to any ARFCN and may be at any frequency. In the exemplary embodiment shown in FIG. 3, DL 1 11368.doc 14 1375476 carrier 1 is not 1) anchored carrier, and UL carrier 1 is represented as a UL anchor carrier for call setup. In other words, the mobile station can receive system information from the BCCH on the DL anchor bearer, transmit the request on the UL anchor bearer, and receive the resource assignment from the AGCH on the DL anchor bearer. The DL anchoring carrier can also be used to carry PTCCH/D and PACCi^ mobile stations for mobile stations to receive data on all N DL carriers or subsets thereof. The link TCH^ mobile station can transmit data on all rivers 1/carriers or a subset thereof. For example, a mobile station may receive a semi-static assignment of multiple (eg, two) UL bearers, but may be allowed to transmit only during any given transmission time interval by an uplink state flag private (USF) based schedule. A subset of the plurality of UL bearers (eg, one UL bearer), wherein the transmission interval can be the duration of the radio block. This allows the gsm network to control which UL carrier is used by the mobile station within the radio block granularity. Data and signals can also be sent on the downlink and uplink in other ways. The (these) carriers for each link can be used to transmit audio, packet, video, and/or other types of data. Each type of data can be sent in one or a few Temporary Block Streams (TBFs). Tbf is a physical connection between two rr entities (for example, a lighting station and a base station) to support data transfer. TBF can also be called data stream, data stream, packet stream, line power, link control (10) turbulence, or some other terminology. Different levels of quality of service (QoS) can be achieved for differences based on underlying data. Q〇s can be quantified by delay requirements, peak data transfer rates, average data transfer rate transfer options, and so on. For example, due to the time sensitivity of the audio (4), the sound (4) can have short delay requirements, fixed data transmission rates, and best effort delivery. The packaged material] 11368.doc 1375476 can be delivered with a longer delay requirement.

. Can support a TBF. In multi-carrier operation, the TBF can be configured with - or multiple time slots of - or multiple carriers. A data connection with different (four) levels can be sent in parallel using multiple TBFs. These TBFs can be sent in a variety of ways. In one example of the invention, Na is isolated by the vector. For example, a single can be sent on a per-carrier. Another example' and multiple TBFs with low Q〇s can be multiplexed onto the carrier to improve relay efficiency. This (4) embodiment can be used in the QgS program. In another exemplary embodiment, the TBF can be transmitted on more than one carrier. This exemplary embodiment may allow the TBF to achieve frequency diversity. Streams, time slots, and vectors represent multiple dimensions that can be used for data transfer. Data for different applications can be mapped to streams in a variety of ways. In addition, the data in each stream can be transmitted in a variety of ways in the assigned time slot and carrier.

Peak Data Transfer Rate and Guaranteed Two Figure 4A illustrates an exemplary embodiment of a data transfer mechanism 41 in a multi-carrier operation. In the example shown in Figure 4A, four packet data blocks eight through D are transmitted on four carriers! Each packet data block is processed (e. g., formatted, encoded, interleaved, split, and modulated) to produce four bursts. In the exemplary embodiment shown in FIG. 4At, four of the four consecutive TDMA frames η to n+3 on the carrier are used for four packets of the same index. Sent in the time slot. Therefore, the bursts A1 to A4 for the packet A are transmitted on the carrier j, and the bundles for the packet B are sent to the B4 to transmit the bundle 'for the packet c' on the carrier 2 to be transmitted on the carrier 3, And used to pack the bundle of D to! ^々 is sent on the carrier 4. This example IJ1368.doc -16-1375476 provides a time diversity for each packet data block. Figure 4B shows an exemplary embodiment of the data transfer mechanism side of the multi-carrier operation #. In this exemplary embodiment, in all four carriers! Up to 4, the four bursts for each packet block are sent in one slot of a tdma frame. Therefore, the plexus for the packet A is arbitrarily arbitrarily arbitrarily transmitted to the four vectors on the four carriers of the nt. The four truncations in the acknowledgment (four) called the eight frames η + 1 are sent on the four carriers of the nt. Bulu am warfare developed on Zhao, used for packet C to send C to C4 *TDMA frame n+2 on four carriers, and used for packet D to send m to D4 in simple frame n+ The four carriers in 3 are sent. This exemplary embodiment provides a frequency common In ^ knife set and also reduces the transmission delay of the parent packet data block. Figure 4C illustrates an exemplary embodiment of a data transfer mechanism 43 in a multi-carrier operation. In this exemplary embodiment, four bursts for each packet data block are transmitted in four time slots of four TDMa frames on four carriers. This exemplary embodiment provides time and frequency diversity for each packet data block. Multi-carrier operation can be designed with moderate degradation, which can be variously degraded.

#式定量. First, the 'action station should not lose me' - pending calls, in case DL .. and / or UL stipulates that the carrier is lost. Secondly, when the DL and/or the fixed carrier are lost, the mobile station should still be able to transmit and/or receive data at a lower rate. The mobile station can detect the loss of the DL bearer based on the signal level and/or signal quality of a DL bearer. The mobile station can report that it has lost the carrier. This report can be event triggered by, for example, after crossing a quality threshold 111368.doc 1375476. If required, the GSM network can switch the dl anchor carrier so that signals can be sent (e.g., timing advance) to ensure proper operation. If the mobile station is assigned two carriers for a given link and the anchor carrier is lost' then the secondary carrier can automatically become the new anchor carrier. If the mobile station refers to more than two carriers and the anchor carrier is lost, one of the auxiliary carriers can automatically become the new anchor carrier. The secondary carrier for each link can be ranked by the GSM network and/or mobile station (e.g., based on channel quality).

Whenever the anchoring carrier is lost, the optimal secondary carrier (e.g., the highest level secondary carrier) can become a new tin carrier.

The GSM network can handle the handover of the anchor bearers in the assigned bearers for each link. This switching can be performed in a manner to reduce the risk of losing the signal. For example, the mobile station may send a signal to the gsm network when it misses the timing advance sent on the PTCCH/D on the D]L anchor carrier, and may then listen to the ptcch from the best or designated DL auxiliary carrier. /d timing advances. If the action specific signal is only sent on the DL fixed carrier, the GSM network can keep the signal in the DL anchor carrier at the same time, and can send the signal β and the bamboo sand for the kiss after the handover is completed. For the simultaneous audio and packet data. For audio + packet data calls, audio (or audio and packet data) can be sent on the anchor carrier, and the message can be sent on - or multiple auxiliary carriers. If necessary, the audio is also moved from the carrier to another carrier to achieve the desired performance. For example, if the quality of the carrier of the audio deteriorates and the quality of the other carrier improves, then: Switch to the improved carrier. As another example, if the carrier is lost, then H368.doc • 18- requires that the audio can be saved via carrier exchange and can be sent on the best available carrier. The switching of the carrier for the audio can track the switching of the anchor carrier or can be switched independently of the anchor. The lamp stage can measure the DL bearer assigned to the mobile station, the DL bearer for the servo base station, and/or the dl bearer for the adjacent base station. These! The measurement can be for the received signal level (RXLEV), the received signal quality (RXQUAL), the average bit error probability (MEAN_BEp), the bit error probability, the diamondization coefficient (CV-BEP), and/or other values. Rxlev is described in 3GPP TS 45.008, entitled "Digital cellular telecmmunications system (Phase 2 + ); Radio subsystem link c〇ntr〇1" (version 6, 2, 5 June), which is publicly available. RXQUAL, MEAN BEp, and CV_BEP. These measurements can be used to assign DL bearers to mobile stations for link adaptation and/or for other purposes. Link tunable representation is based on the transmission capability of a given radio resource@ Select the appropriate rate (eg, coding rate, modulation mechanism, and block size). The action port can be measured and reported in various ways. In an exemplary embodiment, action σ is for each carrier assigned to the mobile station. The measurement is performed and a measurement report is sent for all assigned DL bearers. The mobile station can transmit on the uw fixed carrier - carrying the single-tTL information for the measurement report of all DL bearers. The mobile station can also be in UL Sending an independent measurement report message on the secondary carrier. ^ A ^ In another case, the mobile station only performs the measurement for the DL anchor carrier: the measurement and the report are placed. In the embodiment, DL The quality of the auxiliary carrier mm body can be inferred from the quality of the DL cat carrier. The mobile station can also measure the subset of the DL ancestor of the finger, > β ^^ κ and report it 1 】 1368.doc ~ The power station can transmit the measurement report periodically for any DL carrier and every time a change is detected. In the above various exemplary embodiments, the ~ ' 仃 台 has a The DL anchor carrier and the UL erroneous bearer are assigned to transmit a certain signal on the downlink and uplink respectively. In another example & X %, the anchor bearer is not used for downlink and uplink. Link. For example, the DL bearers can operate independently of each other and the UL bearers can also operate independently of each other. See the bearer can be associated with the bearer carrier so that signals can be sent on each link to facilitate multi-carrier operation. In the other exemplary embodiment, 'an anchor carrier is designated for downlink' but no field assignment is specified for the uplink. In another exemplary embodiment, the m bearer is used for the uplink, but The Wuxi fixed carrier is designated for the downlink key.

TCH, PTCCH, PACCH, FCCH, SCH, BCCH, RACH, and AGCH are some of the logical channels supported by GSM. These logical channels are mapped to the physical channel. The multi-directional proximity mechanism in GSM is TDMA, where each bearer has eight basic physical channels. The physical channel is defined as a sequence of Τ〇μα frames, a number of slots/indexes in the range of 〇7, and a hopping sequence indicating the particular carrier for each TDMA frame. The GSM network can use frequency hopping to reach the component set. As indicated by the frequency hopping sequence, the physical channel hops between carriers in different TDMA frames by frequency hopping. The frequency hopping for a bearer assignment is described in the above 3GPP TS 05,01. In the case of a single bearer assignment, although multiple bearers are available for data transfer in different TDMA frames, the data is only sent on one of the carriers in a given TDMA frame. If frequency hopping is not utilized, the hopping sequence indicates the same bearer for all 111368.doc • 20· 1375476 TDMA frames. In the case of multiple bearer assignments, the data can be sent on multiple pieces in a given TDMA frame. Frequency hopping for assignment of multiple bearers can be performed in a variety of ways. In an exemplary embodiment, each of the multi-carrier assignments hops in the same manner as the physical channel in the single bearer assignment. In this example, a multi-carrier assignment can be considered to consist of multiple assignments of a single physical channel for a single carrier. In other exemplary embodiments, multiple physical channels in a multi-carrier assignment may hop in different ways. Figure 5A illustrates an exemplary embodiment of a frequency hopping mechanism 5 1 , in which multiple (e.g., four) physical channels hop based on a single hopping sequence. Each block in the figure represents a TDMA frame of a carrier. The number in each block indicates the physical channel being transmitted in the TDMA frame of the carrier of the square. In the exemplary embodiment shown in Figure 5A, the carrier for physical channel 1 in the tdma frame η is determined by a frequency hopping sequence and is denoted Ci(n). The carrier for the physical channel k (k = 2, 3, 4) in the TDMA frame η can be given by: Q(«) = {[C,(«) + L2] mod 4} + 1. In this exemplary embodiment, the physical channel is isolated by a fixed distance across the frequency, except when wraparound occurs. For example, 'physical channels 1 and 2 are isolated by a carrier, physical channels 1 and 3 are separated by two carriers, and so on. Figure 5B illustrates an exemplary embodiment of a frequency hopping mechanism 520 in which multiple (e. g., 'four) physical channels hop based on different hopping sequences. The carrier for each physical channel in each TDMA frame is indicated in the figure. In the exemplary embodiment shown in Figure 5, the physical channels are isolated by variable distances that vary between TDMA frames. H1368.doc • 21 * 1375476 In general, frequency hopping for multiple physical channels in a multi-carrier assignment can be achieved in various ways by one or more hopping sequences. The hopping is such that the physical channels used for the mobile station do not collide with each other and do not collide with physical channels assigned to other mobile stations that communicate with the same base station. • The mobile station can have a single receiver or multiple receivers. Each receiver can be coupled to a separate antenna, or more than one receiver can share a common antenna. Each care receiver can process the downlink signal from the base station. If φ can use two receivers, the mobile station can use these receivers during handover and cellular unit reselection to increase data throughput and/or reduce interruptions. When in the traffic state, for example, if the signal quality of the target base station is better than the signal quality of the servo base station, the mobile station can perform the handover from the servo base station to the target base station. When in the interim state, the mobile station can perform the selection from the servo base station in the GSM network to the GSM network or the cellular unit of the target base station in the 3 (31) 1) or 3 (} 2 network.
